y IMPROVEMENT 4IN FURNACES FOR HEATING PURPOSES.

Specification forming part of Letters Patent No. 70,874, dated November12, 1867.

To all whom it may concern:

Be it known that I, JABEZ MAUNTON, of the city, county, and State of NewYork,have invented a certain new and useful Improvement in Furnaces, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, and in which- Figure 1 represents a vertical longitudinalsection of a furnace constructed according to my improvement; Fig. 2, avertical transverse section through the line in Figs. l and 3; and Fig.3, a horizontal section through the line z z in Figs. 1 and 2.

Similar letters of reference indicate corresponding parts.

The nature of 1n\ novel combination of fuel or combustion chambers, foroperationen the base-burning principle of action, with regenerators orregenerating-chambers and passages in connection therewith, undercontrol of a valve for reversal of the draft, whereby great economy isinduced, an intense heat maybe produced, and the durability of thefurnace is preserved. This, my improved furnace, is designed to beapplied to heating purposes generally in7 cluding the heating of steamand other boilers.

Referring to the accompanying drawings,

Arepresents the outer walls of the furnace,

and B its roof. G C are fuel-chambers therein, supplied, say, throughapertures ct a' in the roof, or otherwise, at or near their top, whichopenings may be arranged in a removable cover, D, for distribution ofSuch feeding and distributing arrangements-may, however, be changed,according to the purpose for which the furnace is designed to be ap- 4plied.

rlhese fuel or combustion chambers O O are formed by a centraltransverse partition, S, extending downward from the roof, but stoppingshort of the bottom of the furnace, so as to establish communicationbetween them below, and other transverse partitions E E prothe heat,

jecting from below, but stopping short of the roof, and establishingupper communications with regenerators or regenerating-chambers F F',containing any suitable refractory material, arranged Aeither in regularor irregular order, for circulation of the draft throughl them, andretention of the heat.

rlhese regenerators are represented as of a vertical character, beingprovided with lower inlets and outlets, c c', opening into passages GG', controlled by a slide or valve, H, which, accordingly as it isadjusted to the right or left, serves to make the passages Gr inlets oroutlets, by admitting the air or blast through the one, and establishingthe draft or escape through the other.

By this means, and alternating the position of the valve, isthe currentreversed through the furnace, to impart. the heat passing off with theescaping products of combustion, or unconsumed gases, alternately toeach regenerator, and whereby there is not only great economy, but anintensity of heat may be generated, as will be readily perceived bythose acquainted with the working of furnaces on the regeneratingprinciple of action generally.

But this, my improved furnace, has special advantages. Thus, both by theconstruction or arrangement of the combustion-chambers, to work on thebase-burning vprincipleof acand arrangement of the regenerators, givinga downward course to the heated gases as they pass to or throughthem,the upper portion of the furnace is preserved from rapiddestruction, though an intense heat be kept up in the fuel-chambers orbase portion of the same, to the more f all perfect Vcombustion oinflammable gases, or the few of which that are not there consumed maybe ignited above` Wise confine myself to any particular descrip withsaid chambers at or near their tops, for
